Dataset
DAY-tuh-set
/ˈdeɪtəˌsɛt/

The story behind the word. The word 'dataset' is a modern compound, combining 'data' (from Latin 'datum', meaning 'something given') with 'set' (from Old English 'settan', meaning 'to place'). It emerged in the mid-20th century as computing became more prevalent, describing a collection of data treated as a single unit for processing, effectively a 'set of given things'.
